IMPROVEMENT 'INMACHINES FOR TURNING THE EDGES OF'CLOTH.

Specication forming part of Letters Patent No. 17,224, dated May 5, 1R57.

To all whom, t may concern:

Be it known that I, JOHN P. lvIARsroN, of Charlestown, in the county of Middlesex and State of Massachusetts, have invented a new and useful Machine for Turning the Selvages or other Edges of Cloth, for sail-making and other purposes; and I do hereby declare that the following is a full, clear, `and exact description of the same, reference being had to the accompanying drawings, making apart of this speciiication, in which* Y Figure l'is a longitudinal vertical section, showing all the working parts of the machine. Fig. 2 isa planpof the same. Figs. 3, 4, 5, and 6 are transverse vertical sections of different portions of the machine.

Similar letters of reference indicate corre-l sponding partsin the several gures. y This invention-consists in a novel combination of guides and rollersv for turning over and pressing down the edges of cloth. It is particularly applicable to the business of sailmaking, but may be employed in other operations.

To enable others to make and use my invention, I will proceed to describe its construction and operation. 4

A is ahorizontal table, having a stationary straight guide-piece, a., extending along one table, as shown in the transverse sections, Figs. 3, 4, 5, and 6.

B is an adjustable straightedged guidepiece, that can be secured upon the table A at any distance from the stationary guide-piece a by set-screws or their equivalents passing through slots b b in the table. This adjustable guide-piece is intended to be set parallel with the edge of the stationary guide-piece a., and at a distance therefrom equal to the width of the piece of cloth whose edge is to be turned, minus the width of the margin that is to be turned with the edge.

C, Figs. l, 2, and 3, is a roller with an' upright axis, having a single journal at the top fitted into an arm, D, which hangs over the edge of the stationary guide a, near one end of the table A, said roller having a iiat bottom, but having its sides slightly concave, and being free to rest with all its Weight upon the table,l

with its lower edge nearly close to the face of the .stationary guide a. This roller is to give the rst part of the turn to the edge of the cloth as it is drawn or otherwise moved over the table in the direction ofthe arrow shown in Fig. l, with one edge against the guide B, and the said rollereoines into operation on the cloth almost as soon as it arrives upon the table,l causingthe edge next the guide a; to turn upwardagainst the said guide, as shown in Fig. l, in which, as in all the other figures, the cloth is shown in red outline. T

E is a guide, consisting of a thin plate of metal attached to a stationary arm, F, which hangs over the edge of the guide a, the said guide E ,standing in a vertical position and nearly close to the faceof the guide a., not being quite parallel therewith, but being a little closer at the end farthest from the roller C, so as to make the space between it and the face of the guide a slightly tapering. The marginal portion of the cloth, which has been turned up` by the roller C, passing between the guide a and that E, is flattened, and the turn brought more nearly to'an angular form.

G (see Figs. 1, 2, and 4:) is a stationary frame secured to the table A, and containing two j ournal-boXes for a roller, I, which has its axis arranged parallel with the table, but ina direction transverse thereto, the said journalboxes having springs .s s applied to them to press the roller `down upon the' table. The roller I runs so close to the face of the guide a that it presses the cloth closely into the angle formed between the face of the said guidevand the face of the table, and thus completes what has been partially done by the guide Irl-viz., l

brings the turn in the cloth to a sharp angular form. The above roller derives motion through the friction of the cloth as the latter is drawn along the table. Y

H, Figs. l, 2, and 5, is another guide, ar-

ranged near the face of the guide a, but not quite parallel therewith, the end nearest the roller I being nearest to the face of a, and'in fact almost or quite touching the same. This guide H, `which is attached to a swinging arm, J, so as to enable it to rise and fall freely, is made of a wedge shape in its horizontal section at the end next the roller I, as shown at c in Fig. 2, and at the same end the lower face is beveled transversely, shown at d in Figs. l Mis the barrel, and N the driving-shaft, of

1 and 5; lbut the remaining'portion of the lower face islat, and parallel, or nearly so, with the table. This guide commences the turning down of the marginal portion turned up by the ,two rollers, C I, and plate-guide F. Y The turned-up marginal portion of the cloth, oming in Contact with the sharp wedge-shaped end c, is pushed away from the guide t a, and

- as the oloth advances the said marginal porryingka roller, L, of similar character, and hav` ing pressure applied to it in a similar manner,

for the4 purpose of pressing down iiat the marginal vportion that has been turned down by the successive operation of the roller C, guide E, roller I, and guide H.

a Windlass at the end of the table neXt the roller L, for the purposes of drawing the cloth along to effect the turning of the edge and of winding it up as fast as it is finished. This windlass has on its barrel a fixed iange, e, whose faoe is in the same plane with the guide a, and also a movable flange, f, which' is always ad justed to bring its face in the same plane as the faoeor edge of the movable guide B.

What I claim as my invention, and desire to secure by Letters Patent, i srIhe combination of the guides a and B, roller C, guide E, roller I, guide II, and roller L, substantially in the manner and for the purpose specified. v v
